2 Lifting process BEFORE YOU LIFT Plan Your Route: Path clear? Trip hazards removed? Dry?Assess the Load: Too heavy? Can I use a hand truck or forklift? Can I slide it?WHEN YOU LIFTLift It Right: Position your body close to the object. Keep your back straight.Move It Right: Don't twist your back.Lower It Right: When you put the load down, bend your knees not your waist.GET HELP IF YOU NEED ITWork Together: Don't be a hero. Communicate with your partner!
3 Plan ahead Size up the load: Can it be split into multiple loads?Smaller loads cause less strain on the back.Can you slide it rather then lift?Use material handling equipment if load is too heavy:ForkliftsHoistsDollies9b
4 Plan aheadAvoid using lower rack for moderately heavy to heavy items or awkward items.Get help when lifting heavy, awkward, or long items.9a
5 Basic rules of good lifting Size up the load before you lift.Can you lift a corner?Can you get to the item?Do you need to move somethingto gain better access?1a
6 Basic rules of good lifting Bend your knees.Get a good hand hold.Center yourself over the load.Lift straight up - let your legs do the work.Don’t twist or turn.1b
7 Basic rules of good lifting Have a clear path.Set the load down properly.Always push a cart or dolly.Get help for long loads.Split up heavy loads when you can.Pushing a load is easier on the back; easier to control.1c
8 Never twist or turn when lifting Adds strain to the back’s discs, muscles, ligaments, tendons.Plan your lift to avoid awkward positions.Set load down if you’re losing your grip.Don’t twist and turn or juggle load to regain grip.Keep back as straight as possible.5a
9 Carrying the load Ensure a clear path. Ensure a place where load can be set down.Check for stability of load.Can you get a good grip?6a
10 Carrying the load Use mechanical equipment if load is too heavy. Get help if load is too heavy - lift at the same time to keep load balanced.6c
11 Lowering the loadBend the knees to let leg muscles support the weight.Slowly lower it; do not drop the load.Avoid sudden movements.Lower the load at the same time if working with a partner.7a
12 Awkward Lifting Lifts that are: Above the shoulders Below the knees At arms’ length

16 Reducing heavy lifting Use mechanical assistancePneumatic conveyor
17 Reducing heavy lifting Slide instead of lifting
18 Principles for reducing frequent lifting Use mechanical assistanceAvoid unnecessary liftingUse mobile storage shelvesList of principles to reduce frequent lifting (reducing duration of lifting will also be discussed later)
19 Reducing frequent lifting Use mechanical assistance…… instead of lifting by hand
20 Reducing frequent lifting Use mobile storage:Parts stay on racks as they move from one manufacturing process to the next.
21 Principles for reducing awkward lifting/ Reaching Remove obstaclesSlide closerReduce shelf depthReduce package sizeUse mechanical assistanceTeam liftingList of principles to reduce awkward lifting – reachingAlong with object weight, lifting frequency and duration, the distance between the hands and the low back when lifting is one of the main factors in determining whether a lift is a hazard or not. The longer the reach required to lift an object, the more of a load it places on the low back and the greater the risk of injury.

31 Reducing awkward lifting/ Twisting Use conveyorsAllows boxes to be unloaded and checked in with minimal lifting
32 Lifting techniques training Teach lifting techniques to employees:Training alone is not effective.Making changes to jobs and equipment is better.Making changes along with training is most effective.
33 Lifting techniques training Job-specific, on-site, hands-on training is more effective than classroom.Have employees demonstrate proper lifting techniques before “graduating.”Being trained where they work, using the objects they typically lift and the equipment they use on the job helps employees to relate to what they’re being taught, rather than showing them a generic lifting video.Make sure that employees have learned what you’re trying to teach them by having each one of them demonstrate the lifting techniques properly before leaving the class. Follow-up with them to make sure they are able to use the techniques on the job.
34 Other factors in back injuries Age of employeeImproper postures when sleeping, standing, sittingPhysical condition of employeeRepetitive motions10a
35 Conclusion When lifting a box, think out of the box! Is there a better way?Don’t wait for someone to get injured before changinga job.Just because we have done it this way. Do we have tocontinue to use the same method to handle a loadingand unloading of materials?
